The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of surf coming up for Jaconé, but it’s not all firing on all cylinders. The good news is that after a slow start, the swell shows up, and there are some proper sessions to get excited about.

The first few days are a bit of a mixed bag. Tuesday the 4th is a write-off, with small, weak energy and messy conditions. Wednesday morning the 5th is where it starts to get interesting. We see a clean 3ft groundswell from the south, with a period of 12 seconds, and a light offshore breeze. The water is warm at 73°, which is about normal for this time of year. The combined energy is moderate (617), but the conditions are set to be very good. That’s the pick of the first week.

Thursday the 6th brings a bit more size in the morning, 5ft, but it’s a short-period windswell (7 seconds) from the east-northeast, so it’ll be a bit lumpy and less powerful. Friday the 7th is similar, with a 5ft east-northeast swell, but still short-period. The weekend is a bit of a washout with onshore winds and building, messy south swell. Sunday the 9th has *size*, with a 6ft south-southwest groundswell, but the cross-onshore wind kills it. The energy is strong (1165), but it’s not for paddling; the setup might be more interesting for the kite crew.

Now, here’s the real standout. Tuesday and Wednesday the 12th and 13th of August. Starting Tuesday morning the 11th, we already have a clean 6ft south groundswell (12 seconds) with a light offshore breeze. The combined energy is very strong (967) and the conditions are set to be very good. This is a proper session. Wednesday morning the 12th is even bigger, with a 7ft south swell (12 seconds), moderate offshore wind, and energy climbing to 1381. This is getting into expert-only territory, but it’s going to be a beast. The offshore wind and long period groundswell will make for some powerful, hollow waves at the right spots. This is the best on offer, no question.

The second week sees a bit of a drop-off, but there are still some good clean windows. Friday morning the 14th and Saturday morning the 15th both have 5ft south groundswells (12 seconds) with light offshore winds. Very good, clean, consistent surf. Then, on the 19th of August, we get one more big pulse. Wednesday morning the 19th brings a 6ft south-southwest groundswell, glassy conditions, and a combined energy of 916. That’s a late, promising surprise.

So, to sum it up: the first standout is Wednesday morning the 5th for a clean, fun, smaller longboard session. The absolute best, however, is the Tuesday 11th through Wednesday 12th of August – that’s the big, clean, powerful south swell for the experienced crew. Don’t sleep on the 19th either, that late groundswell looks special.

Rusty out.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
